iPhone 6S and iPhone 6S Plus are here and since the pre-booking is started, lots of people are already booking these two devices. If you are not having an iPhone already then it is okay to be impatience for the new and shiny Apple iPhones.

But what if you are already having an iPhone? Specially the newer models like the iPhone 6 or 5S? Do you still feel the need to buy the iPhone 6S? Since Apple products are well known to be very expensive, it is a good idea to first check whether you really want and need them or not. Maybe most of your requirements can be fulfilled with the iPhone 6 or iPhone 5S itself.

So it is better to compare the latest iPhones thoroughly with the older versions to see which iPhone you should buy and whether to upgrade from the existing one or not? Here is a nice Apple iPhone infographic which compares all of the iPhones in detail to let you know which device is the most suitable for you, whether you should buy an iPhone or upgrade from an older version of iPhone to new one.

So which iPhone are using and are you planning to upgrade to the new iPhone 6S? Feel free to share your views in the comments section below.
